Application filed December 1 1911. Serial No. 666,305.

l '0 a whom it may concern Be it known that I, Atro'us'r (lus'rnr Dine LIN, a citizen of the United States, and a resident of Seattle, county of King, and State of lVashington, have invented certain new and useful Improvements in Shingle- Cutting lvlachines, of which the following is a specification.

The principal object of this invention is to provide a machine of the character indicated which while occupying a minimum floor space and running at low speed yet has an exceedingly large output owing to the large multiple block system. A further object is the safety element, due, in part, to the low speed.

A further object is the saving oft material, due to the use of very thin saws which is in turn due to the low speed.

A still further object is the improved block setting and conveying means. It is not new in the art to provide means for carrying the blocks, from which the shingles are cut, in a continuous direction, the saws being in the path of movement oi the blocks, and I do not claim same without qualification but in machines of this character the number of block carriers and saws has heretofore been necessarily limited thus keeping down the capacity of, the machine and at the same time necessitating high speed, thick saws, danger to the operator, etc. I avoid all these undesirable results by means ot the combination and arrangement of the parts as will be more fully pointed out in the following specification and shown in the accompanying drawings in which Figure l is a side elevation with parts broken away. Fig. 2, a plan view with some ot the timbers broken away. Fig. 3. is a side elevation of one of the block carriers with one of the wheel boxes broken away to show the gearing. Fig. 4 a plan view of one of the links and its attached wheels. Fig. 5, an edgewise view of Fig. 3, looking in the direction of the arrow in Fig. 3. Fig. (3, a cross sectional view of one of the links ta ken upon the line of Fig. 4. Fig. 7, an end view of one of the block carriers and its attached parts, partly in section upon the line g of Fig. 3. Fig. 8, a side elevation of one set of block carriers arranged to swing.

Fig. 11, an end elevation of the :tramc work of the machine partly in section and with parts omitted.

The supporting structure is formed by the inner :trame A and the outer frame B. The tramc A consists ot the two side timbers, l and l joined at their respective ends by the cross timbers 1 and 1. The ends 2 and 2 of which project beyond the plane of the timbers 1 and 1. To the projecting ends 2 and 2 are mortised or otherwise firmly secured the upper side timbers 3 and 3 and the lower side timbers 3" and 3 respectively, secured to the ends of which are the cross timbers 4: and 4;. The timbers 1 and 1 at each side of the frame A lie one above the other and are spaced apart vertically by the upright posts El and 3 (Figs. 1 and ilxtending from one of the posts 3 to the other upon the one side, and from one of the posts 2 to the other upon the opposite side are the stringers l ;'\t. the right hand end o t the frame T5 are the cross pieces 5 and 5 through which pass the bolts 5 and between which and the cross timbers t and t are the springs 5. The frames A and B are sup ported upon the legs or uprights t3 and 6 which are secured to the sills G which are in turn tirmly secured to the base or floor line T. Upon the crosspicces 5 and 5 at one end oi the Frame and 4 and 1- at the oppo site cud thereof are the journal bearings R in whicl are rerolubly mounted the upright sliat'ts .l to which are secured the upper and lower bull wheels '10, the upper pair of which have the teeth 11 which mesh with the miter gears 12 secured. to the shafts 13 which are revolubly mounted in the bearings it upon the lower sides oi the timbers 1 and l.

F ecurcd to the inner ends (it the shafts 1 are the bevel gears 15 which mesh with the similar gears 16 keyed to the sha'tt 17 which is revolubly mounted in the bearings IR upon the under sides of the timbers 1. shown in dotted lines in Fig. 2. The bevel tzcari: It) ha \c the spools l9 t'ormed on their outer ends which are straddled by the iingcrs E20 projecting downwardly from the rod 531 which is s-ihi't'tahle in the bearings 22 secured to the timbers f) and '1 respectively. To the lracket 23 is pivoted the lever 94 to the upper end of which is pivotally con- .ncct'cd the end oi the rod 21 so that by pulling or pressing upon the lower end of the lever 24t the rod 21 is shifted in its bearings and its straddling fingers 20 cause the gears 16 to slide along the shaft 17 to bring either one or the other of the gears .16 into mesh with the miter gears 15, as will be understood. To the 17 is secured the pulley 25'afound which isthe belt 26 which passes downwardly and around the pulley 27 secured to the shaft 28 which latter revolves inthe bearings 29 secured to the base or floor line 7. Loose upon the shaft 28 is the Wheel 30 around which passes the belt 31, driven by the motor 32". Between the pulley 27 and "thewheel 30 is the friction clutch block 32, (Fig. 9') which is loose upon the shaft 28"ai1d to which the wheel 30'is connectedby th-e'heoked fingers 33 which project'intothe recesses 3a in the clutch block 32'sothat by means ofthe lever 35 the hooked finger 36 of the link 37 may be forced against the clutch block 32 to move the sa me int frictional engagement with the pulley'27, alnc by a reverse movement to withdraw the same from such engage- ""llhe hooked finger 36 Wipes around in the annular channel. 38 of the clutch fiecure d to the shaft 28 is the wheel 39 arotinfd passes the belt 40 thecourse of which is in the direction of the arrows 1 and is over the drum 4E1 dewn wardly an claroiind the drum 42, thence to left' over the. i'dler43, downwardly d thedrum44,"' 'etiirni11g upwardly dve the drum 45 and finally'down to the whiiel The drums 41 4.2; 44 and 45 andthe tate 4s ils cure to the cross shafts 0;," Z (Z and '6 respectively; which shafts rev olye in'the bearings 45 secured the timbers T9 one en'd of the shaft (0 is secured th e saw 4th, to the shaft 5 secured thesaw l't', to the shaft 0, is secured the saw tot-he shaft (Z is secured the saw 49. To the tinder stirfaces of the til nb ers 3 and 352' and to the upper surfaces ofthe timbers and 3.. are secured the track rails 50 upon wheels 5l mounted within th"heXfes"52 uphnthe links53 joined t0- gether the pins 54 which pass through the. heles 55 (Figs. 3 and a). The links 53 are curred as shown, to readily pass around b 11wt1ee1s10,"and have the ledges 56 which fit oyer the'upper circularedges of the iifheels''10, A shoulder 57 is formed at the end of ejachfof these ledges (Fig. 4;) which coeperatetz with the studs 58 (Fig. 2 ira-91 the wheels Prawn; r s l ping of the ehaln thus formed by the connecting links The chain thus formed passes around the bull wheels 10 as plainly shown F gs. I and 2. After these chains have been passed around the wheels 10 the same are drawn to the proper tension by moving the cross timbers 5 and 5 in or out by means of the bolts 5 and their cooperating nuts the springs 5 pressing outwardly on the timbers 5 and 5 as will be understood' Between the upper and lower links 53 are the rods 59 upon which are slidably mounted the upper and lower shingle block keepers 60. To the upper block keeper 60 is attached the link 61 which passes through the slot 62 in the upper link 53 and through which is the pin 54. The upper block keeper 60 is downwardly pressed by the springs 63, the pin 54- forming a limit stop therefor. The block keepers 60 are recessed at 64 (Fig. 7) to receive the toothed rods 65 which are reduced at either end to revolubly the bearings formed by the ends er of the recess 64:, these ends being correspondingly reduced (Fig. The block keepers 60 are vertically bored at one end to revolubly receive the spindles 65? and 65", the former having flat tension spring 65 and the latter the spiral spring 65, and upon both are formed the worm'igears 66 (Figs. 3 and 5), which mesh with the similar gears 67 upon the ends of the rods 65. Upon the ends of the spindles 65: and (35 are the pinion wheels (SSthe teeth of which are in the vertical plane of the pins 69 and 69 which are removably mounted in the brackets 70 and 70 securedto the upright timbers 71 of the frame A. Upon the wheel box 52 pivoted the lever 7 2 (Fig. 3) the lower end of which is pivoted at 72 to the link 61 and upon the upper end of the same is'the roller "(2 which passes under the plate 73 (Figs 1, 2 and 11) which is held' up by the spring 73 attached to the bracket 73 upon the timber 3. Pivoted to the plate 73 is the lever 7d which is pivotedto the bracket (Fig. 11). To the lever 74 is pivoted the lever 75 which is bent at right angles as shown, and projects outwardly where it terminates in'the foot piece 76f "W' hen the parts" are in the positions shown in" Figfl the rollers 72? justpass beneath the plate 73. i

lVhileT have shown but a limited number of block carriers 60 and their attached mechanisms, it will be understood that upon each of the "rods 59 a block carrier may be mounted in the manner above described.

"To conveniently remove the saws 46, 47, 48 and t9 for repairs,"or for other reasons, I swingingly mount one'o r more sets 'ofthe block carriers 60. as illustrated in Fig. 8. Referring particularly to' that figure, the left hand rod 59 instead of entering the upper and lower links 53, is mounted in the plates was shown in dotted lines in Fig. 8. The plates 78 swing upon the right hand rod 59 in the manner of a door, and the up- I The lever 72, instead of being permanently pivotedv to the link 61 is removably connected thereto by the pin 81 and notch 82 so that when it is desired to open or swing the block carrier 60 all that is necessary is to spring the lower end oi the lever 72 slightly outward and then lift the same clear of the upper plate 78, when the upper and lower block car'iers 60, plates 78, and the left hand rod 59 may be -freely swung outwardly from left to right upon the right hand rod 59. To firmly secure the parts in position I provide the semicircular lastenings S3 revolubly mounted upon the pins 84 and which fit into corresponding openings in the ends of the plates 78, as plainly shown in Figs. 8 and 10, the operation of which is obvious.

From the foregoing description it is be lieved that my device will be fully under stood by those skilled in the art. A shingle block is placed between each pair of the upper and lower carriers 60, the toothed rods 65 indenting into the block and holding the same firmly under pressure of the springs 63. Power is transmitted from the engine 32 to the wheel 30 and its attached shaft 28 and, through the clutch mechanism illustrated in Fig. 9, further transmitted through the pulleys 27 and 25, belt, 26, shaft 17 miter gears 15 and 16, shait'ts l5), miter gears 12 to the bull wheels '10. The chains formed by the links are carried around by the bull wheels 10, the wheels 51 rolling upon the tracks 50 during their straigl'it forward movement, and being supported by their ledges 56 (Fig. 6) upon the wheels 10 as they are carried around the latter. The wheel 39 being also attached to the shaft. 28, power is transmitted t-herethrongh and through the belt 40, drums it and 4.2, 4 .1.- and 45 and their attached shatts a, 7), e, (Z, to the saws 46, 4-7, 48 and 49, the saws 4-6 and 4-9 turning in one direction and the other two saws turning in the opposite direction. As the shingle block, previously adjusted between the carriers 60, passes the first saw in its path a strip is cut from its face. Before the block reaches the next saw the pinions 68 must pass the pins 69 and G9, the former, as will be observed in F 8, being fewer in number than the latter causes the lower pinion wheels 68 to rotate through a less distance than the upper wheels 68 and causing a corresponding difference in the rotation of the upper and the lower toothed shafts 65 in the block carriers 60, which feeds the upper end of the block a certain distance toward the vertical plane of the saw which it is approaching, and the lower end of the same a certain less distance, which, when the block passes the next saw causes a properly shaped shingle to be cut therefrom. The block is again antomatically set as the pinions 68 pass the next set ol pins (39 andtlf)" and so on until the block has been reduced to a spawlf By pressing downwardly on the toot piece to of the lever the plate T23 is forced downwardly and slightly below the plane of the upper portion ot the approaching roller 72". As the roller TL passes under the now depressed plate 73 the upper block carrier (30, through the lever 72, pin 72 and link (31, is drawn upwardly against the tension oi the springs 63 and so hold while the roller 72" is passing under the plate T3, during which the spawl. may be readily removed and replaced by a fresh shingle block. Due to the tact that the lines of blocks when traveling in their cutting path are parallel to each other, the saws running vertically and the block setting mechanism intervening between the saws, much less space is occupied by the machine than if the blocks traveled in a circular path and the saws were an anged in a horimntal plane. It is obvious that the output of the machine is large; that the same may be run at low speed which permits the use of thin saws and at the same time saves material.

While I have shown a particular form o't cu'il'nuliment ot my invention, 1. am aware that many changes (herein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention, and I do not, thel'e'tore dc sire to be limited to the exacttorm and ar rangcment herein described and shown in the drawings.
